NSE IPO Puts Exchange Valuations Under the Spotlight as BSE Trades at a Higher P/E Multiple Despite NSE’s Dominance in Equity Trading

The upcoming IPO of the National Stock Exchange (NSE) has brought the valuation of India’s two leading stock exchanges into focus. While NSE remains the dominant player across cash equities and equity derivatives, BSE is trading at a higher price-to-earnings multiple, raising questions about the factors driving the valuation gap.

Analysts attribute BSE’s premium to its faster earnings growth from a smaller base, improving operating leverage and opportunities to gain market share. NSE, meanwhile, brings substantially larger revenue, deeper liquidity and an established position in derivatives trading. The comparison highlights why exchange valuations cannot be assessed solely through market share or headline P/E ratios.

NSE IPO Valuation Stands at Around 42.9x P/E

The NSE IPO is scheduled to open for subscription on September 17 and close on September 21. The price band has been fixed at ₹1,700–1,785 per share.

According to SBI Securities’ estimates cited in the report, NSE is being offered at a projected valuation of around 42.9 times earnings. NSE’s Red Herring Prospectus (RHP) puts BSE’s P/E at 54.28 times, based on the reported comparison.

The IPO is entirely an Offer for Sale (OFS), with up to 12.64 crore shares being sold by existing shareholders. No new shares are being issued by NSE, meaning the proceeds will go to the selling shareholders rather than directly to the company.

BSE’s Earnings Growth Supports Higher Valuation

Santosh Meena, head of research at Swastika Investmart, said BSE trades at a clear valuation premium to NSE, with BSE at roughly 50–60 times FY26 earnings compared with NSE’s IPO pricing of around 40–43 times.

He attributed the difference primarily to BSE’s faster earnings growth from a smaller base. BSE has gained market share in equity derivatives, particularly options, which has increased its options premium turnover and transaction revenues.

NSE’s larger base and regulatory changes affecting some segments have moderated its growth rates in certain metrics. This has led investors to assess the two exchanges differently, with BSE being valued partly on its growth potential and NSE on its established scale and profitability.

NSE Maintains Significant Market Share Advantage

NSE continues to hold a dominant position in India’s equity markets. According to the company’s RHP, its FY26 revenue stood at ₹16,601 crore, compared with BSE’s ₹4,834 crore.

NSE’s average daily turnover in the cash segment is nearly 13 times that of BSE. The gap is even wider in equity futures, reflecting NSE’s substantial share of trading activity.

In cash equities, NSE holds approximately 93 per cent of the market, leaving BSE with considerable room to expand. However, NSE remains the largest exchange in the derivatives segment, where its established liquidity and market infrastructure provide a significant competitive advantage.

Options Trading and Market Share Drive Revenue

BSE’s growth in equity derivatives has been a key factor behind its improving financial performance. The exchange has gained share in options trading, increasing its options premium turnover and transaction revenue.

NSE, on the other hand, retains a substantial share of the options market and continues to benefit from its scale. Its revenue generation is supported by high trading volumes, strong liquidity and established participation from institutional and retail investors.

Deven Choksey, managing director of DRChoksey FinServ, described the valuation difference as a liquidity premium. He noted that smaller companies can experience higher growth rates because of the low-base effect, while larger businesses typically have more moderate growth.

NSE’s Scale and Profitability Remain Important

Despite BSE’s higher valuation multiple, NSE has several structural advantages. The exchange is the world’s largest derivatives exchange by contracts traded, according to the report, and has a much larger revenue base than BSE.

Its deeper liquidity, higher margins and stronger operating scale contribute to its earnings power. NSE’s established position across cash equities, futures and options provides a significant foundation for its business.

Meena said NSE’s valuation reflects slower near-term growth expectations, regulatory headwinds and the absence of a listed scarcity premium once the IPO is completed. He also noted that the exchange’s larger scale and profitability could support a premium over time, depending on future earnings growth and market conditions.

Market Share, Earnings and Valuation Need to Be Assessed Together

Analysts believe the two exchanges should be valued using a combination of absolute earnings power, sustainable growth rates and market-share trends rather than relying solely on P/E multiples or trading volumes.

BSE’s growth potential in cash equities and derivatives may support further earnings expansion, while NSE’s scale and dominant market position provide a different set of advantages. The two companies operate in a market where liquidity, technology, transaction volumes and regulatory changes can materially affect revenue.

Choksey said the exchange business is unique, with both BSE and NSE occupying important positions in the Indian capital markets. He argued that the two exchanges do not necessarily need to be valued directly against each other.

NSE IPO Could Influence Exchange Valuations

The NSE IPO will provide public-market investors with a direct opportunity to assess the valuation of the country’s largest stock exchange. The offering may also bring greater attention to BSE’s market valuation and the factors driving its premium.

The listing could provide a more transparent market reference for NSE’s equity value, although the IPO pricing and subsequent trading performance will depend on investor demand, earnings expectations and broader market conditions.

Market Outlook

The valuation comparison between BSE and NSE highlights the importance of distinguishing between growth potential and established earnings scale. BSE’s improving operating leverage and opportunities to gain market share in cash equities and derivatives are central to its valuation story, while NSE’s larger revenue base, deeper liquidity and dominant market position provide a different foundation for investor assessment.

Investors will track the NSE IPO subscription response, the final listing valuation and future financial performance of both exchanges. Market-share trends, options trading volumes, regulatory developments and the sustainability of earnings growth will remain important factors in assessing the valuation gap.
